Abstract: An air connection pipeline device of a massage pool may comprise a pipeline. The pipeline may be formed with a first air connection passage and a second air connection passage. The first air connection passage may have a first air inlet and a first air outlet. The first air connection passage may include a check valve located between the first air inlet and the first air outlet. The check valve may be driven to open when the air flow moves from the first air inlet to the first air outlet and close when reversely. The second air connection passage may be provided with a switch valve. The switch valve may comprise a second valve core and a second elastic body. The second valve core may slide between a closed position to close the second air connection passage and an open position to open the second air connection passage. The second elastic body may press against the second valve core. An initial state of the second valve core may be the closed position.

Abstract: An airway structure of a massage pool may have a compensation function. The airway structure may comprise a pipeline, a control valve group, an air connection sleeve, a first elastic body, and a second elastic body. The pipeline may comprise a fixed air connection portion and a sealing plate. The control valve group may comprise a control plate. The control plate may be located under the sealing plate. The first elastic body may be attached between the pipeline and the control valve group and abut against the control valve group to make the control plate abut under the sealing plate. The fixed air connection portion may be provided with an air connection port. The air connection sleeve may translatable relative to the air connection port. The second elastic body may be mounted between the air connection portion and the air connection sleeve and abuts against the air connection sleeve to make the air connection sleeve abut under the control plate.

Abstract: A SPA machine includes a housing provided with a water sprayer, a water pump mounted in the housing for pumping water out of the water sprayer, and a pressure-balancing watertight electric control device formed of a box, watertight buttons, an electric control unit, a watertight panel and a locating frame and mounted the housing for controlling the operation of the water pump and having a variable inside space automatically regulated subject to the external water pressure to prevent water penetration and to avoid electric leakage.

Abstract: A hydrotherapy jet includes a jet body having an open upstream end and an open downstream end and defining a flow path between the open upstream end and open downstream end, a flapper disposed within the flow path, the flapper having upstream flapper and downstream flapper ends and rotatably connected to the jet body at the upstream flapper end to rotatably oscillate about the upstream flapper end when a stream of water is introduced from upstream to downstream through the flow path and a head spoiler formed on the downstream flapper end to reduce the frequency of oscillation of the flapper wherein a stream of water pulsating effect is felt by a user of the jet apparatus adjacent the open downstream end as the flapper rotatably oscillates.

Abstract: A portable hydro massage device for submersion in a body of water containing a female user, i.e. a bathtub, provides a local massage to the labium region and a focused stimulant to the female user's clitoris thereby resulting in a superior sensation to the entire body promoting an overall euphoric state and calming effect. The apparatus employs a saddle shaped housing, where the buttocks are placed, and a saddle horn for controlling the stimulus. Disposed within the midsection of the saddle horn is a hydro jet with a driven flow from a circulating water pump that draws suction from the main body of water. The hydro jet is adjustable in pressure and a method is provided for aeration of the water discharged to allow for a rhythmic pulsation effect. The saddle horn may be held and the lower body positioned as needed to focus the discharged stream from the hydro jet to the desired point of the pelvic region.

Abstract: A pedicure foot bath is provided having a removable water moving module. The water moving module of the present invention comprises a rotating paddle which simulates an ocean-like wave motion which soothes and relaxes sore, tired and injured feet.
